Abstract
The utility model belongs to a printed wiring board has copper hole locating plate, including a plurality of printed wiring board (2), it has copper hole (1) for 3.0mm to be equipped with the diameter in the three angle department of printed wiring board (2), its characterized in that a plurality of printed wiring board (2) bond on phenolic aldehyde backing plate (7) uniformly, be equipped with between the angle of four angles of phenolic aldehyde backing plate (7) department and each printed wiring board (2) link bit hole (6) of no copper, be equipped with in an angle department of printed wiring board (2) and prevent staying hole (8), be stained with adhesion binding dust paper (5) on each printed wiring board (2). The utility model discloses an it only has copper hole orientation problem to have solved the printed wiring inboard, and it has copper hole to decrease the defect to have improved, the efficiency of the printed wiring board production that the size is little is improved, the phenolic aldehyde backing plate has been saved, the cost is reduced.
Description
Technical field
The utility model belongs to the processing method of electric circuit board, and particularly a kind of printed wiring board has copper hole location-plate.
Background technology
At present in printed wiring board manufacturing process, 2-4 is generally needed to select in set to locate without copper location hole, to meet the technical requirement of user to printed wiring board.Four diameters can only be processed at four angles place with regard to existing printed wiring board and have copper location hole at 2.5mm.The defect of this printed wiring board does not have the plate without copper location hole, this mode cannot be selected to locate processing, can only select the plate of copper location hole, so just easily produces the damage of location hole; In addition when the printed wiring board of manufacture order size < 50 × 50mm, because typesetting is too much, shop bolt uses too much, easily causes production efficiency to decline; Simultaneously phenolic aldehyde backing plate due to pin intensive, useful life reduces by more than 50%.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of and made by adjustment gong band, in upper berth, plate face blue dust sticky paper, improve shaping production efficiency, the printed wiring board saving phenolic aldehyde backing plate has copper hole location-plate.
The technical scheme that the utility model technical solution problem adopts is: a kind of printed wiring board has copper hole location-plate, comprises multiple printed wiring board, and being provided with diameter at three angles place of printed wiring board is that 3.0mm has copper hole; It is characterized in that multiple printed wiring board is bonded on phenolic aldehyde backing plate equably; Between four angles place and the angle of each printed wiring board of phenolic aldehyde backing plate, be provided with the connection bit hole without copper, be provided with fool proof hole at the angle place of printed wiring board; Be stained with on each printed wiring board and adhere to dust sticky paper.
The beneficial effects of the utility model are: this utility model solves in printed wiring board only copper hole orientation problem, have improved hole, copper hole and have damaged defect; Improve the little printed wiring board production efficiency of size, save phenolic aldehyde backing plate, reduce cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is the front view that printed wiring board has copper hole location-plate;
Fig. 2 is without the front view adhering to dust sticky paper in Fig. 1.
In figure: 1-has copper hole; 2-printed wiring board; 3-retains connection bit; The half of groove of 4-; 5-adheres to dust sticky paper; 6-connection bit hole; 7-phenolic aldehyde backing plate; 8-fool proof hole.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of printed wiring board has copper hole location-plate, comprises four printed wiring boards 2, and being provided with diameter at three angles place of printed wiring board 2 is that 3.0mm has copper hole 1; It is characterized in that four printed wiring boards 2 are bonded on phenolic aldehyde backing plate 7 equably; Between four angles place and the angle of each printed wiring board 2 of phenolic aldehyde backing plate 7, be provided with the connection bit hole 6 without copper, be provided with fool proof hole 8 at the angle place of printed wiring board 2; Be stained with on each printed wiring board 2 and adhere to dust sticky paper 5.
Described printed wiring board has the processing method of copper hole location-plate to take following steps: a. is bonded with four pieces of printed wiring boards 2 equably on phenolic aldehyde backing plate 7; B. process at four angles place of printed wiring board 2 three diameters be 3.0mm have copper hole 1 and a fool proof hole 8; C. carry out the connection bit hole 6 retaining four angles place of printed wiring board 2 when gong band makes, its half of groove 4 gong is fallen; D. be stained with on track wiring board 2 and adhere to dust sticky paper 5, gong is except the connection bit hole 6 without copper on printed wiring board 2.
When not boning adhesion dust sticky paper 5, being provided with between four angles of phenolic aldehyde backing plate 7 and the angle of each printed wiring board 2 and retaining connection bit 3, connection bit hole 6 will be processed on reservation connection bit 3 after bonding adheres to dust sticky paper 5.
When this printed wiring board has copper hole location-plate to use, the phenolic aldehyde backing plate 7 between each printed wiring board 2 is cut off, becomes single plate and use.
